  • Method and system for location based communication service
    Publication number: 20070287474
    Abstract: A system and method for location based communication includes an access network for communication and a first access terminal configured to determine and report a position of the first access terminal. A location services server receives and stores the position report, compares the position of the first access terminal to a geographic zone definition, and sends a location match message if the position of the first access terminal is within the geographic zone definition. A communication server maintains a call domain, receives the location match message, and, in response, sets-up a call when the first access terminal is included in the call domain.
